JOURNAL-BOX FOR STEAM-ENGINES.

SPECIFICATION forming part of Letters Patent No. 440,102, dated November4, 1890.

Application filed July 12, 1890. Serial No. 3581560- (N0 model.)

To all whom it may concern.-

Be it known that I, GEORGE FUSSELL, Jr., a citizen of the United States,residing at Lockport, in the county of Niagara and State of New York,haveinvented certain new and useful Improvements in J ournal-Boxes forSteam- Engines: of which the following is a specification,referencebeing bad therein to the accompanying drawings.

This improvement relates more particularly to the main bearing ofsteam-engines, but it may be found useful in other engines or machines;and the invention consists in the peculiar construction, arrangement,and combination of parts hereinafter more particularly described andthen definitely claimed.

In the accompanying drawings, Figure 1 is an elevation of one end of anengine-frame provided with my improvement partlyin section. Fig.2 is avertical central longitudinal section of the same. Fig. 3 is an end viewwith parts removed. Fig. 4 is a perspective view of a section of the boxremoved. Fig. 5 is a perspective of a movable pillar, whose object willbe more fully described hereinafter.

Referring now to the details of construction, A represents the frame ofthe engine, having an opening a to contain the box and to which the capB is secured.

At 0 (see Fig 5) is shown a pillar provided with a lug c, which fitssnugly into a hole a, bored into the back of the opening a. On thispillar is set one half of the box D, which is provided with a groovedrib on the back to fit on the half-round surface of the pillar O. Theother half of the box is of similar form and sets on a pillar similar tothat shown at O, which pillar is attached in a similar manner to the capB, as shown at Fig. 2 and then the cap is securely bolted on, as shownat E in Fig. 1, thus holding the engine-shaft F in a box that isperfectly self-adjusting as to position. By this construction a bearingfor a steam-engine shaft is made that will enable said shaft to run easyeven if the pillow-block that carries its other end gets considerablyout of line either vertically or horizontally, and thus heating andexcessive wear of the journal and box will be prevented, for it isevident from the construction described and shown that the box andpillars practically form a self-adj usting bearing that will accommodateitself to any change of position of the shaft.

\Vhat I claim as new is 1. The combination of a box D, having ribs onits back, and a holder for said box engaging with said ribs andconstructed to move on a pivotal point in its support, substantially asdescribed.

2. The combination, with a divided box D, each section having a grooveon its outer surface, of the pillars O, fitted to said grooves andsupported on central pivots, substantially as described.

3. The combination, with the frame of an engine, of a divided box D,each section having a grooved rib, and a pillar O, fitted to said grooveand provided with a pivotal lug c, fitting into holes in the frame ofthe engine, substantially as described.

In testimony whereof I aflix my signature, in presence of two witnesses,this 9th day of July, 1890.
